This is my second time here. I stayed for a few weeks. The accommodation was comfortable and felt like a private home. There are some kitchen appliances to cook breakfast or lunch, including a microwave and full-size refrigerator. The staff came by every few days to bring new towels and gave a little cleanup every week.
The neighborhood is great ... not too far from bustling Silom Also, though, there were many restaurants on the nearby sois. Silom Complex has a good grocery store for supplies.
All in all, I'm glad I stayed here. There was a convenient table and office chair so you can get your work done and a comfy couch to watch TV when you are finished. Drinks and massages are nearby, but the side street location made the place pretty quiet except at midnight when the municipal trash collectors drive their big truck on the small street.
Sanunsorn answered my messages quickly and graciously helped me finding availability amongst the other guests. I highly recommend this place.
